On many instruments, this has been set to `-2147483648` to effectively disable the minimum-gap checking. This can
also be set temporarily.

### Settings are suspected to have changed recently

Not all motor record fields are archived, however their values are saved in autosave files.

An easy way of seeing whether a field has changed recently, is to use `grep` and look in the file contents. As the files are suffixed with the time they were created this effectively gives a time record of when things happened:

For example in this case we want to see the `UEIP` field of `MTR0102`. First open a git bash session (which works over ssh):
```
"\Program Files\Git\bin\bash.exe"
```

then:

```
grep -rnw '/c/Instrument/var/autosave/GALIL_01' -e 'MTR0103.UEIP'
```



### Position needs to be restored
